If I'm really angry, hurt, or stressed, I usually cry out swear words in exasperation. I try very hard not to swear, in all politeness, but an occasional bad word or two comes out of my mouth. I never, EVER swear around my family though. I don't want them involved with my occasional bad habit. I don't say the F word and all that. Now that is just wayy too extreme, rude, and unnecessary.
